The brushless DC water pump plays an important role in daily life. It can make the pump suck low-level liquid or water into the pump cavity at a high place and throw the liquid out at a high speed through the impeller, so as to achieve the purpose of transporting and promoting the liquid. If the brushless DC water pump is sometimes unqualified or the service life is too long, and the self-priming ability is reduced, it will not achieve the purpose we need. Therefore, it is particularly important to understand and master the methods to improve and increase the self-priming ability of the brushless DC pump. important.

1. The brushless DC water pump is equipped with a vacuum pump on the suction pipe of the water pump. Before the pump is started, the vacuum pump is started first, so that the suction pipe of the water pump is filled with water first to ensure that the pump starts automatically and quickly. This type of water absorption requires a complete automatic control system to ensure normal operation.

2. The brushless DC water pump reduces the bends of the inlet pipe, the height of the drop and the horizontal interval.

3. The brushless DC water pump is equipped with a suction tank before the pump.

4. Install a suction bottom valve at the end of the suction pipe. The suction bottom valve is actually a check valve. It ensures that the water flow can only enter the suction pipe from the pool and cannot flow back. Therefore, if the suction pipe is full of water, although the pump axis is higher than the working water level of the pool, it is because there is water absorption. The function of the bottom valve prevents the water in the suction pipe from flowing into the pool, so that the suction pipe is always filled with water, ensuring that the water pump can be started automatically and quickly.

The above is how to extend the service life of the brushless DC pump and improve its self-priming ability. Hope to provide some help to your operation and use.
